2 Claims. 1

This invention relates to an adapter for screen cloth or other sheetmaterial and it is an object of the invention to provide an adapter tobe mounted about the perimeter of an opening to provide a ready andconvenient means whereby said opening may be covered tightly and neatlyby a screen fabric or other sheet of desired material.

It is also an object of the invention to provide an adapter thatobviates the present need of a frame or the like about an opening to beso coveredrand the existing material forming the opening is suitable toreceive the adapter and need not be milled as would :be necessary ifthis adapter were not used.

A still further object of this invention is to provide an adapter thatmay be secured to the material forming the boundary of any opening thatacts as a superior framework for screen fabric or the like holding thefabric very taut with tension both laterally and vertically.

In order that my invention may be better understood, I will now proceedto describe the same with reference to the accompanying drawing,wherein:

Figure 1 is a fragmentary view in perspective of an adapter constructedin accordance with an embodiment or" the invention applied to a frame ofwood or the like for placement within a wall opening;

Figure 2 is an enlarged fragmentary sectional view taken substantiallyon the line 2-2 of Figure l; and

Figure 3 is a view similar to Figure 2 but illustrating the adapterapplied to a metallic member of the frame for placement within a wallopening.

In the embodiment of the invention as illustrated in Figures 1 and 2 ofthe drawings, I denotes a member of a frame F to be snugly received witha wall opening and which member may be of wood or other material thatmay be penetrated by a screw 2 or the like.

An adapter A embodying the invention is to be positioned along the innermarginal portion of a member I with the ends of adjacent adapters Amitered, as at 3, or otherwise formed to allow said adjacent ends tohave close contact. Each adapter may be separate or independent of theothers or adjacent adapters A may be suitably connected as therequirements of practice may prefer. v

Each adapter A, as herein disclosed, comprises `an intermediate plate 4for close contact from end to end with the inner edge face a, of a stripI This plate 4 is also of a length coextensive with the length of theface a and of a width through.-

out its length to extend a material distance across the face a.

A longitudinal margin of the plate 4 is deiined bly-an outwardly andlaterally directed plate or fiange 5 which has close contact with a sideface b of the member I. The adapter A is held in working position on itsmember I ,of theframe to the plate 4. This, however, may be varied asthe necessities of practice may require.

The second or inner longitudinal margin of the plate 4 is defined 'by arelatively narrow ange and herein shown perpendicular to the plate 4.This iiange 6 is disposed in a direction opposite to that oi the plateor flange 5 or in a direction inwardly of the frame F when the `adapteris applied.

The outer longitudinal margin of the flange 6 is dened by a flange 1which is spaced inwardly of the plate 4. This iiange 'l is hereindisclosed substantially parallel to the plate 4 and of a Widthmaterially less than the width of the plate 4.

The outer longitudinal margin of the iiange I is continued by a revertedstrip 8 which lies close against the inner face of the flange 1. Thestrip 8 is of a materially less width than the width of the flange 1,whereby the free longitudinal edge of the strip 8 provides an inwardlyfacing shoulder 9 o-r shoulder which is opposed to the flange 6.

The flange S, and the plate or ange 1 together with the plate 4 providea pocket to receive a marginal portion of the screen fabric or sheet I Idisposed over the opening of the frame F. This marginal portion isrolled around a key I0 of plastic or other suitable material and whichkey I0 is preferably pliable to facilitate assembly. The key III is alsoof a length substantially equal to the length of the flange 0 and ofsuch diameter from end to end to hold the rounded portion of the screeninwardly of the shoulder 9 and to press the fabric or sheet against theplate 4 whereby the sheet o-r fab-ric Il is tightly held by the adapter.

The key I0 can be readily applied or removed and thus allowing suchadjustment of the portion of the sheet or fabric I I disposed around thekey IIJ to be adjusted as required to assure the fabric or sheet I Ibeing tight across the opening of the frame F.

As illustrated in Figure 3 the adapter A is simi..

lar in structure to the adapter as previously described. However, theadapter A is applied to a metal member I2 of the frame B for the wallopening and the outer plate or flange 5 of the adapter is spot Welded,as at I4 to an outer face c of the member l2 of the frame B.

As clearly illustrated in the accompanying drawings the various plates,flanges and strip of the adapter A is formed from a single length ofsheet metal of requisite gauge.

From the foregoing description it is thought to be obvious that anadapter for screen cloth constructed in accordance with my invention isparticularly well adapted for use by reason of the convenience andfacility with which it may be assembled and operated.

I claim: i

1. In an adapter for holding a marginal edge portion of a screen fabricto a member of a frame, a length of U-channel metal having the outersidewall thereof of agreater Width than the inner side Wall, a flangeout-turned from the free edge portion of the outer side wall, means forsecuring the ange along the inner face and. edge of the frame member, areinforcing portion over-turned inwardly from the free edge of theinner'side wall and into abutting relation with respect to the innerside of the latter wall, and a key of circular cross-section engagedwithin the channel behind the free edge of the rein- 3 forcing portionand with the marginal edge portionof the'fabric to clamp the latterbetween'the same and the walls of the channel.

2. An adapter for holding a marginal portion of a screen fabric to amember of a frame, comprising an elongate plate to :be secured along theinner face and edge of said frame member, an outstanding flange integralwith and extending along the inner longitudinal margin of the plate, asecond plate integral with and disposed along the outer margin of theflange and extending parallel with respect to the first platev to'form achannel therewith to receive a marginal portion of the fabric, areinforcing portion overturned OTHER REFERENCES The following referencesare of record in the le of this patent:
